Definitions
- the present invention relates to a method and apparatus for embedding and presenting tissue samples for histological examination and, more particularly, a method for preparing a tissue sample for microscopic examination.
- a procedure ' for preparing tissue samples for microscopic examination by embedding the tissue in paraffin and slicing the paraffin-embedded tissue into thin layers with a microtome for mounting on a slide is well known in the art.
- the tissue is pretreated in various solutions selected in accordance with the particular examination being conducted.
- the tissue sample is fixed, dehydrated, cleared, infiltrated with molten paraffin and, depending on the test, stained.
- the sample In order to impregnate the tissue sample, the sample is dehydrated, most commonly with isopropyl alcohol, and then immersed in liquid paraffin.
- the step of paraffin impregnation normally takes place at ambient pressure and at a temperature slightly higher than the melting point of the embedding material .
- the melting point lies approximately between 50 degrees C. and 58degrees C.
- the replacement of the isopropyl alcohol contained in the tissue of the tissue samples with paraffin is effected by dissolving the isopropyl alcohol in paraffin such that the concentration of the paraffin increases in the tissue sample.
- the paraffin solidifies, thin sections can be sliced from the tissue samples embedded in paraffin block, mounted on a slide and examined under a microscope.
- McCormick in U.S. Patent 5,665,398, discloses a system for providing an embedded tissue specimen subsequent to fluid treatment of the specimen and preparatory to histological examination.
- the system includes the combination of a cassette for use in the preparation of tissue specimens for histological examination and an embedding mold having a first cavity for receiving the treated specimen and a second cavity for receiving the cassette.
- the system includes means for dispensing a predetermined amount of molten wax into the embedding mold.
- U.S. Pat. No. 5,080,869 to McCormick describes a cassette for efficiently processing tissue samples.
- the cassette is stackable and can be used for preparing a plurality of specimens.
- the cassette generally includes a plurality of apertures disposed in the walls of the cassette for passage of processing fluids in a direction both orthogonal and parallel to the plane of the bottom wall of the cassette.
- the cassette also includes a sloping extension of the front wall of the cassette for ease in placing indicia on the cassette for identification of the sample.
- a sloping extension of the front wall of the cassette for ease in placing indicia on the cassette for identification of the sample.
- a problem with the prior art methods of embedding and sectioning tissue is the clumping of cells such that cells of interest may not be present in a particular field of view. It is, therefore, desirable to have a method for preparing tissue for sectioning such that cells comprising the tissue are more or less evenly distributed on the section mounted on a slide thereby improving the probability of a particular cell type of interest being present in a particular section and field of view.
- Figure 1 is a schematic diagram illustrating the sequence of steps used for tissue sample preparation in accordance with the present invention.
- Figure 2 is a longitudinal cross-sectional view of a preferred embodiment of a pipette operable for forming a cylindrical tissue specimen suitable for sectioning.
- Figure 3 and Figure 4 are schematic diagrams illustrating the sequences of steps of a preferred embodiment using a number of bore holes .
- a tissue sample 10 is prepared for embedding in a solid or semisolid support such as, for example, agarose or paraffins, by immersing the tissue in a suitable fluid medium, or a series of fluid mediums 11, to dehydrate and/or clear the tissue.
- the dehydrated tissue is then transferred into a volume of molten paraffins 12 and the tissue, which may comprise a cell line, fragmented and disbursed throughout the volume of melt by cell dispersing means 13 such as a sonicator or mechanical agitator.
- cell dispersing means 13 such as a sonicator or mechanical agitator.
- the paraffin/cell slurry is extruded through a warm motion less mixer tube section before entering a cold tube section.
- the resulting endless plug is homogeneous.
- Motion less mixers are commercially available tubes or pipes, which force the flowing material to mix while passing various internal obstacles .
- the tubes often have series of flow dividers placed in different angles in the tube.
- the tube can be part of a continuous sonicator allowing for large scale homogenizing of the hot and flowing paraffin/cell melt.
- a pipette 15 having an axial bore is employed to draw the volume of melt into the bore.
- the volume of melt containing the disbursed tissue is allowed to cool below its melting point within the axial bore.
- the cylindrical plug thus formed within the axial bore may be totally or partially extruded from the pipette for storage and/or sectioning.
- the pipette may also be used to store the tissue.
- the extruded material may also be further processed as required for other examinations of the tissue such as electron microscopy or fluorescence spectrometry.
- the pipette may be placed in a receiver port 20 in a microtome 21 and a thin disc 22 of the plug 14 extruded from the bore as shown in Figure 2.
- a microtome blade 23 is advanced to separate the extruded disc from the plug.
- the disc 22 is then transferred to a support such as a microscope slide 24 for staining and examination.
- the diameter of the axial bore, and hence, the diameter of the plug and disc may be "pin-like", having a diameter of -O.lmm. or "wafer-like", with a diameter of -1.5 cm. or even greater.
- the pipette may be any, preferably rigid, tubular member.
- Preferred materials are glass and rigid or semi rigid elastomers such as polyethylene, polypropylene or polystyrene.
- the means for drawing the melt into the axial bore of the tube include vacuum aspiration, centrifugation and capillary action.
- a preferred means of vacuum aspiration is a plunger 25 slidably disposed within the axial bore of the tubular member. While traditional paraffins may be used in accordance with the present method, a preferred embedding medium is a hydrophilic gel such as agarose .
- the tubular member comprises a polymeric material that remains a rigid at the melt temperature of the embedding medium and is easily separable from itself as, for example, by being sliced by a knife blade.
- the cylindrical plug of embedded tissue within the axial bore of the polymeric tubular member need not be extruded from the bore prior to mounting.
- a portion of tissue is placed into a volume of a fluid embedding medium, then the cells comprising the tissue are disrupted until the cells comprising the portion are distributed substantially homogeneously throughout the volume of molten fluid embedding medium.
- a portion of the volume of the fluid embedding medium is drawn into the axial bore of the polymeric tubular member and permitted to solidify within the axial bore to form a cylindrical plug.
- a portion of the tubular member (containing a portion of the cylindrical plug) is then transversely sliced or otherwise separated from the remainder of the tubular member to form a separated portion.
- the separated portion which includes a thin disc of embedded cells circumferentially bounded by and contained within a ring comprising a portion of the polymeric tubular member, is then mounted on a rigid support substrate .
- a heated or cold metal block (31) with a number of bore holes (32) connected to movable stoppers (33) in one end can each be filled with the same or different tissues or cells in a suitable liquid
- the cells are dispersed evenly in each borehole .
- the metal block is allowed to cool and the liquids solidify in each hole. Applying pressure or pushing (41) the plugs upward or downward partly into a container (42) attached to the metal block the plugs will stand free and in parallel in the container (43) .
- the container (41) is filled with paraffin with preferable a lower melting point and allowed to solidify by cooling covering the plugs (44) .
- the resulting paraffin or gel is cut (45) or sectioned to give a thin slap of paraffin or gel containing slides from each of the plugs (46) .
- the thin slice is mounted on slides (47) and further processed as required for examination of tissues in microscopes .
- the size of the sections can be controlled and the cells comprising the tissue are substantially homogeneously distributed within the plug and, therefore, a section removed therefrom.
- any fluid embedding material that can be solidified after being transferred to the axial bore of the tube such as upon standing, addition of a catalyst to the fluid or UV irradiation may be used in accordance with the present method. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
